CCNA Routing and Switching (legacy) — Question 132

Which command can you enter to determine whether a switch is operating in trunking mode?

Answer options

• A. show ip interface brief
• B. show vlan
• C. show interfaces
• D. show interface switchport

Correct answer: D

Explanation

The correct answer is D, as the 'show interface switchport' command provides detailed information about the switch port, including its trunking status. The other options do not provide specific information regarding trunking mode; for instance, 'show ip interface brief' gives a summary of interface statuses, while 'show vlan' and 'show interfaces' focus on VLANs and general interface details, respectively.
